Welcome to WebmasterWorld thesprucegoose.

For photos you'd just put the image URL into the RSS like this:

<img src="URL" alt="alt text" align="right" />

GeoRSS [georss.org] isn't something I've used before in my feeds, but it doesn't look too difficult. You add your latitude and longitude like this:

<georss:point>34.6861553192139 135.526142120361 </georss:point>

You'll want to use an appropriate namespace for the GeoRSS.

I came across a neat GeoRSS editor [geotwitter.net]. It's an online application and you can generate a GeoRSS feed by pointing and clicking on a map.

Thanks for the response!

That's a fantastic start, but I don't even know how to setup an RSS feed! :(

I know it's an XML file, but how do you get it to automatically add content? For example, a user submits a new photo with his/her geographical location. How do I get the XML file to automatically update with the .jpg file and the <georss:point> meta data?

Thanks again,

You can create RSS feeds manually with a text editor if you like, but if you're looking for something automatic then you'll probably want something like a CMS to generate the feed for you. Most CMS and blog packages will do this for you.

The RSS spec [rssboard.org] is fairly simple. It's an XML dialect, so if you're familiar with web coding it won't be too difficult to grasp.
